In the feasibility study stage, first, Mine Design Institute and the client need to sign the entrustment agreement. After the two sides reaching an agreement, Xinhai Mine Design Institute starts to establish a working group for work including: planning, investigation, data collection, planning and optimization, project evaluation, "report" writing, and exchanging views with commissioned units to form a formal report.
In all the work of the working group to carry out, investigation, data collection and plan optimization is the most important basis for selecting plant construction scheme. For these important parts, the working group requires different professional division and cooperation.
The key to mine design is all must be established on the basis of detailed investigation, and therefore Xinhai Mine Design Institute will firstly take a comprehensive field study to the mine of clients including the crude ore for dressing plant, site, water, electricity, traffic, geography, etc.
After "Feasibility study report" approved, Mine Design Institute starts preliminary design and comes up with the design of dressing plant construction. Design mainly involves dressing, general layout, electric power, communication, civil engineering, environmental protection, water supply and drainage, tailings, safety and fire protection, investment estimates, economic benefit. For the improvement and extension enterprises, the preliminary design will illustrate the status, characteristics, plant, main problems, utilization of main buildings and equipment.
Xinhai Mine Design Institute has many engineers who can design different types of dressing plants (less investment, quick capital return or easy management) according to clients’ requirements. what's more, the design cost is lower than the national standard.
After the completion of the preliminary design, Design Institute experts will gather all content to form the detailed “Preliminary design report " submitted to the competent department of Mine Design Institute
When the preliminary design is approved, Mine Design Institute starts to design working drawings. Every aspect of dressing plant needs a lot of construction drawings (generally, over 100 working drawings), such as civil construction. Engineers of Xinhai Mining Institute are numerous with rich experience and drawing speed. When the working drawings completed, the designers must hand the drawings over to construction commanding officers, especially, the notes, strict regulation and important content.
